Purification of pseudopodia from polarized cells reveals redistribution and activation of Rac through assembly of a ... (7435 words) |
 | Percent pseudopodia growth is the amount of pseudopodia protein on the undersurface of the membrane induced by cells exposed to an LPA gradient relative to cells in the absence of LPA. |
| Whole cells on culture dishes or pseudopodia in the growth and retraction phase were isolated as described in panel a and analyzed for tyrosine phosphorylation by Western blotting with anti-phosphotyrosine antibodies. |

| Amebas constantly change the shape of their bodies as a result of the phenomenon known as ameboid movement, involving the formation of temporary extensions (pseudopodia, or false feet) of the body. |
| Pseudopodia, used in locomotion and feeding, may be rounded at the tip (lobopodia), pointed (filopodia), branched and fused together (rhizopodia), or somewhat rigid and pointed (axopodia). |
| Other ameboid protozoans of the phylum Sarcodina include the marine radiolarians, which form silicate skeletons; their freshwater counterparts, the heliozoans; and the shell-bearing foraminiferans. |
